The Silent Pathogen in Pregnancy with Grave Outcome
Background: Listeriosis is not a commonly encountered infection in pregnancy. The disease causes mild maternal illness but is known to have deleterious effects on the fetus.
Case description: Preterm premature rupture of membranes (PPROM) and meconium-stained liquor (MSL) seem to be the mode of presentation of Listeria in pregnancy. Antenatal diagnosis can be established with blood culture alone if sent suspecting the infection as part of the fever workup. Placental inflammatory response and meconium macrophages in amnion are the diagnostic features on histopathological examination for confirmation. She received third-generation cephalosporins.
Conclusion and clinical significance: Early diagnosis and evaluation of the disease in the mother will prevent intrauterine stillbirth and decrease the risk of perinatal mortality.
